DETAILED DESCRIPTION
[0024] The preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present invention, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.
[0027] In the manufacturing process of LCD products, metal pins are key components used to connect to external circuits. The quality of the glue coating on metal pins directly affects the conductivity and stability of the product. Too much UV glue may cause short circuits between pins or affect the assembly of other components, while too little UV glue may cause the pins to be loosely fixed or poorly sealed. Therefore, accurately controlling the amount of UV glue applied is crucial to ensuring the quality and reliability of LCDs.
[0028] However, in the glue coating process of existing LCD products, it is difficult to monitor the glue coating quality of metal pins due to the lack of accurate glue coating position reference on LCD products. This often leads to problems such as glue coating position offset and uneven glue coating, resulting in unstable product performance and even failure.
[0029] Based on this, the present application provides an LCD metal pin.
[0030] Example 1
[0031] like Figure 1-Figure 3 As shown, this embodiment provides an LCD metal pin, which includes a pin body 4; along the length direction of the pin body 4, marking lines 2 are arranged at the edges of both ends of the pin body 4.
[0032] Specifically, along the length direction of the pin body 4 , the minimum distance between the identification line 2 and the pin body 4 is 2 mm-3 mm.
[0033] Furthermore, along the length direction of the pin body 4, the width of the marking line 2 is 1 mm-1.5 mm.
[0034] In actual applications, the marking line 2 of the present application is made of indium tin oxide (ITO for short). ITO has good electrical conductivity and high light transmittance in the visible light region, which makes it an ideal transparent conductive material. At the same time, it also has strong corrosion resistance and excellent performance.
[0035] The metal pin 41 is provided with ITO identification lines 2 at both ends of the pin body 4. The ITO identification lines 2 have good conductivity and light transmittance, and can be conveniently integrated at the edge of the metal pin 41 of the LCD without affecting the normal use of the product. During the gluing process, the staff can determine the starting point and the end point of the gluing according to the position of the identification line 2, thereby ensuring the accuracy of the gluing position. At the same time, by observing the color change or width change of the identification line 2, it can be judged whether the amount of glue applied is appropriate, so as to adjust the gluing parameters in time to ensure the uniformity and appropriateness of the amount of glue applied.
[0036] By adding identification lines 2 at both ends of the pin body 4 (i.e., at the outermost edge), the coverage of the UV glue during the coating process can be clearly seen. When the UV glue is coated, it should cover and slightly exceed the identification line 2, which indicates that the coating amount is moderate. If the glue does not cover the identification line 2, it means that the coating amount is insufficient; if the glue covers too much and exceeds the identification line 2 by a lot, it means that the coating amount is too much. By observing the coverage of the identification line 2, the production staff can monitor the coating amount of the UV glue in real time and adjust the coating process or equipment parameters as needed. In this way, it can be ensured that the coating amount of the UV glue of each LCD is within the appropriate range, thereby improving product quality and consistency.
[0037] More specifically, the pin body 4 includes a welding pin, a test pin, a ground pin and a fixed pin. Each pin 41 is provided with two opposite connecting plates 42. An insertion port 43 is formed between the two connecting plates 42. The insertion port 43 is fixedly connected to the external lead 3 of the LCD.
[0038] The welding pins are used for welding connection with a circuit board or other electronic components. The welding pins 41 help to ensure a stable connection between the LCD and the circuit board, thereby achieving signal transmission and power supply.
[0039] Test pins are used to perform various electrical performance tests on the LCD. Test pins can include pins for measuring parameters such as voltage, current, resistance, and pins for signal input and output. Test pins are usually located at the edge or specific area of the LCD to facilitate connection with test equipment.
[0040] The ground pin is used to connect the metal part of the LCD to the ground wire of the circuit board to ensure electrical safety and stability. The ground pin can effectively prevent electrostatic interference and electromagnetic radiation, and improve the performance and reliability of the LCD.
[0041] The fixing pins are used to fix the LCD on the circuit board or other structural parts to ensure the stability and reliability of its position. More specifically, the fixing pins usually have a certain mechanical strength and can withstand certain vibrations and shocks.
[0042] Specifically, the number of the connection pins, the test pins, the ground pin 1 and the fixing pins can be set according to the actual size and requirements of the LCD.
[0043] In a more preferred embodiment, the connecting plate 42 is arranged in a wave shape, and is provided with abutting sections 421 connected to the external leads 3 of the LCD, and at least two abutting sections 421 are arranged on the connecting plate 42 .
[0044] When the plug-in port 43 is plugged and fixed on the external lead 3 of the LCD, the abutting section 421 abuts against the LCD, so that the connecting plate 42 and the external lead 3 of the LCD are firmly fixed, thereby ensuring the stability of the installation of the pin 41 and the external lead 3 of the LCD.
[0045] Example 2
[0046] This embodiment provides an LCD display, which includes an LCD body 1 , on which an external lead 3 is disposed, and on which the LCD metal pins as described above are disposed.
[0047] The metal pins 41 of the LCD display for which protection is sought in this application have an appropriate amount of UV glue applied and are firmly fixed, the metal pins 41 have good contact, and the LCD is not prone to reliability and functional problems such as display defects.
[0048] More specifically, the LCD body 1 includes a frame 11, a first substrate 12 and a second substrate 14 that are arranged opposite to each other, the first substrate 12 and the second substrate 14 are arranged between the frame 11, and a liquid crystal layer 13 is arranged between the first substrate 12 and the second substrate 14;
[0049] A light source 17 is disposed on a side of the second substrate 14 facing away from the first substrate 12 . One side of the light source 17 is connected to the frame 11 . The frame 11 is provided with heat dissipation fins 16 corresponding to the light source 17 .
[0050] Specifically, in practical applications, the first substrate 12 may include a stacked substrate 122, a polarizing layer 123, and a functional layer 121, wherein the polarizing layer 123 is in contact with the liquid crystal layer 13, and the functional layer 121 is disposed on a side away from the liquid crystal layer 13. The second substrate 14 includes a stacked substrate 122, a polarizing layer 123, and a reflective film 141, and the reflective film 141 is disposed on a side of the light source 17 away from the liquid crystal layer 13.
[0051] In a more preferred embodiment, a liquid cooling layer 15 is provided between the light source 17 and the heat dissipation fins 16. The liquid cooling layer 15 can transfer the heat generated by the light source 17 to the heat dissipation fins 16, thereby improving the heat dissipation effect of the light source 17, so that the LCD can work stably for a long time.

Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
